The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 631 are 631

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 479 are 479

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 705, 631, 644, 479

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(705, 631) = 444855

GCD(705, 631) = ( 705 x 631 ) / 444855

= 705 / 631

= 705

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

So, Greatest Common Divisor of 705, 631, 644, 479 is 1
